RTF is a global modification that replaces all towns in the game.

I came up with a description for the sisters, maybe you'll like it. As they say, the author's approval is needed.😅

The Sisters of Sorrow are an ancient sisterhood of Erishian necromancers who, during an unsuccessful experiment to turn them into vampires, became immortal spirits trapped in the armor of their order.

The Sisters of Terror are the highest-ranking necromancers who were on the verge of becoming vampires, but now they are unyielding spirits sowing terror in the hearts of their enemies.

(I replaced the names of the Wailing Banshees with Sisters of Grief, I saw it on your VK page). The Sisters of Grief still cannot come to terms with the fact that they are now only the spirits of their former selves, and now their grief is expressed in continuous wailing and screams.

Well, "veteran" and "king" are not equivalent titles.

Okay, I've decided who will complement the faction.

The flies won't go anywhere; they'll occupy Tier 3. Flies hatching from the corpses of enemies, as a special ability of Naadir, is cool.
Rotting Warriors will move to Tier 2. A specialist in warriors is cool; it will be a necromancer-knight.
I used to dress Alaric in the Lich armor from Dark Messiah; that will be Tier 4.
And I can take armor for undead horses from Warcraft, so Tier 6 will feature vampire knights, but not handsome ones, but Nosferatu, although maybe the red grade will be prettier.

I want to make the fly smaller, so it's unicellular; I'm currently trying to transfer its parts to the feathered serpents of Hannik.

Not bad, now it can be put into NCF. There are descriptions for everyone there, but I have my own constantly changing lore, lol.

It's funny that tomorrow will be a month since I've had the NCF Rotting Guardians; I'm too lazy to write descriptions, and at this rate, the necromancer girls will be released in NCF sooner.
